    DRO is short for dielectric resonator oscillator, also known as crystal oscillator, which is a stable and reliable frequency source.

    The main role of broadband dielectric resonator oscillator is to convert a direct current signal into a high frequency AC signal. DRO's high Q characteristics make it act as the role of "microwave crystal oscillator", which is easier to achieve low phase noise of microwave frequency source; DRO has a resonance frequency temperature coefficient can be positive or negative excellent characteristics, greatly improve DRO frequency temperature drift performance; Although DRO cannot achieve broadband multifrequency, it has advantages when working at dot frequency.
    The dielectric resonator oscillator include three types: single channel dielectric resonator oscillator, dual channel dielectric resonator oscillator and triple channel dielectric resonator oscillator.

    Other features include:

    1.High frequency stability: Low noise dielectric resonator oscillatorss have high frequency stability and a small range of frequency changes, making them particularly suitable for high-precision frequency control applications.
    2.High quality factor: The quality factor of the dielectric resonator oscillators is very high, which can generate signals with low harmonics, low interference, and low energy loss, which helps to improve system performance.
    3.High temperature stability: The frequency stability of the dielectric resonator oscillators is good at different temperatures and is not easily affected by temperature changes.
    4.Low phase noise: Compared to other oscillators, low phase noise dielectric resonator oscillators have lower phase noise and generally use noise reduction techniques to further reduce phase noise.
    5.Easy to integrate: dielectric resonator oscillatorss can be used in integrated circuits, with a smaller volume and lower power consumption, suitable for applications that require miniaturization and low power consumption. Due to these characteristics, voltage tunable free running dielectric resonator oscillatorss are widely used in fields such as satellite communication, radar systems, military communication, aerospace, and scientific research.

    Qualwave provide a variety of DRO, frequency up to 38.5GHz, low phase noise, all indicators are good, widely used in many fields.
